I saw in York once, Altoona Model Works operating roundhouse doors. Below is a link to the video showing them working.

That looks pretty complex...and delicate. Did you see the video YouTube recommended after yours? This looks much easier.

Yes, looks like a great idea. If I were to design one I think I would mount the servos or motors under the layout and mount the doors to hinge on rods with a hidden drive.

Similar to double-acting French doors, I know at Thomas Jefferson's house in Monticello, he had a device installed under the floor. It was "a figure-8 bar-and-chain arrangement" that would activate both doors at the same time.
